SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 328,117, dated October13, 1885.

Application filed November 13, 1884. Serial No. 147,879. (No model.)

To all whom it may concern:

Be it known that I, L. ALBERT HELLER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inSpring Bed- Bottoms, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention relates to improvements in bed-bottoms of that class whichemploy transverse slats on which the springs are mounted, and has forits object to rigidly secure and connect the springs at the lower endsthereof to the slats and to each other in sections; and it consists,essentially, of two slats and their springs, the springs being free attheir upper ends and having independent motion, and the sections adaptedto be readily removed from the bed-frame when it is desired to remove,repair, or store the same.

Theinvention consists in the combination and arrangement of parts,substantially as hereinafter described and claimed.

In the drawings, Figure 1 is a top or plan view of a bed-bottomembodying my improvements. Fig. 2 is a side elevation of two slats andtheir springs folded for storage or transportation. Fig. 3 is anenlarged side elevation of a portion of the bed-bottom in position foruse. Fig. 4 is a horizontal section on the line mo of Fig. 3, showing aportion only of the bed-bottom, and Fig. 5 is a detail view.

Similar letters of reference in the several drawings denote like orcorresponding parts.

Referring to the drawings, A designates the bed-frame, having cleatsasecured to the inner surfaces of the longitudinal pieces thereof, and Bdesignates the slats extending from side to side of said longitudinalpieces and fitted in recesses in the said cleats.

G designates spirally-coiled springs, the upper free end of each beingbent in a horizontal plane and connected to the upper coil thereof,while the lower end of the spring is formed into a bracket, 0, the upperhorizontal and vertical arms of which embrace a slat, B, while the lowerhorizontal arm is bent at an obtuse angle to the vertical arm, and isprovided with an upwardly-turned end, 0, which is adapted to bearagainst the under surface of the slat, as clearly shown in Fig. 5. Thesprings of two adjoining slats are connected together by links or rods Dto form sections, one end of each of said links being pivotallyconnected to the lower coil of its springs, as at d, while the other endis hook-shaped, as at d, which is adapted to take over the lower coil ofthe adjacent spring.

It will be observed that each spring of the set is connected to itsfellow on the slat to which it is secured, and also to the adjacentspring on the opposite slat of the set, and that the springs at the endsof the set are held from displacement by the action of its fellow bylinks E, secured to said spring and having its opposite end bent to forma point which is driven into the slat, as shown at 6, Fig. 3, or securedthereto by a staple, 0. (See Fig. 4.)

The bed is provided with six or more slats or three sets; but itsometimes happens. that there is an odd number of slats, in which case Isecure the springs O of the odd slat to the slat and to each other bythe links E and D, and provide the same with rods F, which are pivotallyconnected to said springs and have their hooked free ends take overstaples f in the head or foot board of the bed,thereby firmly securingthe slat and springs in position.

When it is desired to fold the sections of the bottom for storage ortransportation, the two slats composing the same are removed from theframe of the bed, the free ends of the links are disconnected from thecoils of the springs which they engage, and one of the slats is thenturned over, when the springs thereof are passed sidewise into thespaces between the second set of springs, after which the hookshapedends of the links of one set of springs are caused to engage the uppercoil of the other set of springs, as clearly shown in Fig. 2.

It will be observed that my invention provides a bed-bottom which iscomposed of sections which are adapted to be folded for transportationor storage, and that the springs of each section are firmly and rigidlysecured to the slats and to each other, whereby displacement isprevented, the upper ends thereof being free and adapted to actindependently of each other, while at the same time any one of each ofsaid springs can be quickly and easily disconnected from its fellow andthe slat when it has become broken or out of order.

It will be further observed that the brackets 0 of the springs of eachset are bent in opposite directions over the slats, as clearly shown inFig. 4, and that whatever tension thelinks D exert is at the bottom orbase coils of the springs on the slats and in line with the bed frame.

Modification in details of construction may be made without departingfrom the principle or sacrificing the advantages of my invention as, forinstance, two or more slats with their attached springs may be tiedtogether instead of using the links D.

I am aware that it is not new to make the upper coils of a spring ofless pitch than the lower coils, and to connect such springs at aboutthe point where the larger and smaller coilsjoin by means of connectinglinks; also, that two bars with their attached springs have been used toform a section of a bed-bottom.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent of the United States, is

1. A bed-bottom composed of sections, each section consisting of twoslats having springs provided with brackets adapted to embrace the slat,said springs being connected at their lower ends by links D, constructedsubstantially as described, and adapted to be detached at one end only,the upper ends of the springs being free, substantially as herein shownand described.

2. Ina bed bottoni, the combination of the bed-frame, the slats havingsprings secured thereto and connected together by links to formsections, springs O 0, having their ends provided with a point, as 0links D, having one end pivotally connected to one of the springs of oneset, and its hook-shaped end connected to one of the springs of thesecond set, and links E, having one end secured to a spring and itsopposite end to the slat, all arranged and combined as hereinbefore setforth.

In testimony whereof I affix my signature in presence of two witnesses.

L. ALBERT HELLER.
